Highway - Oil Additive for Car Engine - High-Mileage Motor Revitalizant Restore Treatment - for Gasoline, Diesel and LPG Engines, Worn Metal Parts Repair - Atomic Metal Conditioner (Bottle 7.5oz)

This is the third or fourth bottle I've purchased over the past few years, adding one with every oil change when due. I've driven many miles these past few years and this product has taken great care of my engine. Technically, one can is supposed to protect the engine for many thousands of miles but I appreciate the added power and quietness of my engine when I add it to the oil after the oil change. Great product.

👍👍👍

So I followed instructions and let my car sit overnight. Next morning I honestly couldn't believe it ran smoother. It definitely is saving on gas mileage after driving for a few hours. Give it a try.

This is my third bottle for my third vehicle, which I haven't put in yet. Reason, it's a 2006 with 23,000 miles. It might be "all in my head" but the other two seem to be running great.

The engine began to run quieter and smoother.

great thing! I'm happy with it!

This product worked tremendously on my vehicle! The tick that I was receiving while operating my vehicle is 99% gone. Nothing would change the issue I was enduring until I found this AMAZING product!

I often use oil additives in my Mini, sometimes I can tell a difference depending on what I use, this one I can neither recommend nor not recommend. I don't really think it helped or harmed my car. Maybe others will see different results but for my part, I couldn't tell any difference.

Ótimo produto, entrega rápida, pena que não há mais nenhum anúncio deste produto para venda em todo o site da Amazon!

I have a 1997 classic Mercedes SL320. The engine definitely sounds quieter and smoother after trying the Xado.

Es un buen producto, no hace milagros, en mi caso el motor se tragó una pequeña arandela por la admisión y por lo visto fastidio algo, al poner el Xado se notó el motor más fino, no tira tanto humo pero como ya digo, los milagros no existen,pero es un buen producto,ahhh me llegó con un regalo de grasa en spray Xado. 👍

My truck has 410,000 km on it. It’s a Ford F150. You would think being a Ford the motor would’ve let go already, but black luckily it hasn’t.. The motor started making noise as it should with that kind of mileage and I was ecstatic after pouring that into the engine in no time at all that motor sounded almost new. Extremely happy. I will continue to purchase an ad with oil changes.

OK ! Funziona ….
